Configured enclosed drive for industry

Technical documentation  / 

Overview of SINAMICS G120XE

The SINAMICS G120XE is an enclosed drive designed specifically for pumps, fans
and compressors. This rugged drive is based upon the SINAMICS G120X to best
meet the demands of pump, fan and compressor applications, the environment
and the power supply system.

A comprehensive range of pre-designed standard options completes the package.
Additionally, please consult the factory for any custom options that may be needed.

SINAMICS G120XE drives are UL listed to UL508A

usa.siemens.com/sinamics-gxe

Depending upon power ratings, the drive enclosure is either a wall-mounted box or a free­standing enclosure. The most common standard options can be accommodated in the base
enclosure. A few options including output filters and reduced voltage soft start (RVSS) bypass
require an add-on or separate options enclosure.

Attention to detail is evident in the design of the drive. For example, the enclosure ventilation
fans are controlled via a relay to run only when needed, i.e. when the drive is running. Not
only does this save energy costs, but it also reduces noise levels in the electrical room.

UL listing

SINAMICS G120XE is an enclosed drive listed to UL508A.

Operator interface

The door-mounted Intelligent Operator Panel IOP-2 is a high resolution color keypad that is
user-friendly and a powerful operator panel. The IOP-2 allow fast local setup, fault diagnostics
and intuitive operation of the G120X and simplifies the adjustment of settings during operation.
It features an intuitive central multi-functional sensor control wheel.

For pump, fan and compressor applications, the IOP-2 application wizards interactively guide
you without the need to know parameter numbers.

Auto / manual control is done using the membrane keyboard and the central sensor control
field and there is a dedicated local / remote button.

SINAMICS IOP-2

14 interface languages available

Process values can be displayed numerically in technological units. Up to two process values
can be displayed graphically as bar graphs. The IOP-2 also allows graphical trending of values.

Motor and drive sizing

The Service Factor must be considered for motors operating at Service Factors beyond 1.0.
Please consult factory for assistance in sizing the drive.

For motors with ratings larger than the drive, please consult the factory as nuisance tripping
may occur if the drive is not properly sized. In sensorless vector control, the rated motor
current (FLA) must be at least 1⁄4 of the rated drive output current. With lower motor currents,
operation is possible in Volts / Hz control mode only.

Overload ratings

The SINAMICS G120XE may be operated with either light or high overload duties. The criterion
for overload is that the drive is operated with its base load current before and after the overload
occurs. Light overload duty is based upon 110% base load current for 60 sec. within a cycle
time of 300 sec. or 150% for 60 sec. within a cycle time of 600 sec.
